Description

Technical Field

[0001] The utility model relates to the technical field of installation of space display screens, in particular to an installation structure for space display screens. Background Art

[0002] At present, ultra-high-definition immersive experience space is gradually becoming a new innovative application scenario for display screens. For example, some 4D cinemas allow the audience to follow the protagonist to experience special effects such as wind, rain, thunder and lightning, learn about history by showing real battlefields, and truly feel the interior and performance of a car in space.

[0003] Some immersive experience spaces are essentially in a space building, with display screens installed on the walls, ceilings, and floors; the immersive feature allows the audience to no longer be a spectator, but to be fully immersed in it. Through surround sound effects, realistic tactile feedback, and free interaction, the audience feels as if they are in the scene being displayed.

[0004] In the actual construction process, many companies now directly adopt the method of laying LED display screens on the wall, that is, setting up a back frame and installing LED display screen blocks on the back frame - that is, the LED display screen blocks are adsorbed on the front of the back frame by screwing magnetic screws on the back.

[0005] However, existing immersive spatial display screens have the following problems during installation:

[0006] 1. The display screen will vibrate to a certain extent. Specifically, the existing immersive spatial display screen has a back frame including a top frame, a bottom frame, and four side frames, and these six frames together form a rectangular space. These six frames are fixed together, and then the bottom frame is fixed to the ground by screws, and the top frame is connected to the ceiling. When people step on the bottom frame when watching, it will cause the bottom frame to vibrate to a certain extent, thereby causing the LED display screen blocks on the top frame and the side frame to vibrate slightly. In severe cases, the LED display screen may vibrate to a certain extent, so the viewing experience is not good. In addition, this vibration may cause the LED display screen blocks to fall off.

[0007] Second, the adsorption and fixing effect is not good. The current LED display screen blocks are fixed to the back frame by magnetic screws on the back. For traditional wall displays, the reliability is high because no one touches them. However, for immersive spatial displays, since the top frame is also placed on the LED display screen blocks, this fixing method is not reliable enough. If it falls off, it will bring safety hazards, especially when the back frame vibrates when people step on it.

[0008] 3. When multiple LED display screen blocks form a display screen for the entire wall, it is not easy to adjust the flatness. At present, there are mainly the following types of back frames used in the installation of immersive space display screens: the back frame is made of multiple rods welded as needed, and then the welded back frame is fixed on the wall, but this welding method is difficult to ensure the flatness of the back frame on the front; the second type is to gradually connect multiple back frame units into an integrated back frame through bolts, and then fix the back frame on the wall as the front wall. This bolt connection method is also difficult to ensure the flatness of the back frame on the front; if the flatness of the back frame is not good, when the LED display screen block is magnetically adsorbed on the back frame to form a display screen for the entire wall, the flatness of the display screen can only be adjusted by the magnetic screws on the back of the LED display screen block (adjust the length of the magnetic screws on the back of the LED, and then let the magnetic screws be adsorbed on the back frame); but the degree of adjustment in this way is limited, and it still cannot particularly well guarantee the flatness of the entire display screen.

[0009] To this end, our company has made improvements based on the structure of the existing spatial display screen to overcome the above problems. Utility Model Content

[0010] The utility model aims to overcome the shortcomings of the prior art and provide an installation structure for a space display screen, which can prevent LED display screen blocks from falling off, improve safety, and easily adjust flatness.

[0011] The purpose of the utility model is achieved through the following technical solutions: a mounting structure for a space display screen, comprising a side wall frame I, a top wall frame II, and a bottom wall frame III, which together form a rectangular space structure, wherein the inner surfaces of the side wall frame I, the top wall frame II, and the bottom wall frame III are provided with LED display screen blocks, and an adjusting screw B is provided on the back of the LED display screen block, wherein the adjusting screw B is a magnetic screw, and the adjusting screw B is magnetically adsorbed on the corresponding wall frame;

[0012] The inner walls of the side wall frame I, the top wall frame II, and the bottom wall frame III are provided with multiple rows of slots, and the adjusting screws B of the LED display screen block slide into the slots; the large end cap of the adjusting screw B can be adsorbed on the bottom of the slot;

[0013] When there is vibration or insufficient magnetism, the large end cap head of the adjusting screw B can still be stuck in the slot, so that the LED display screen block will not fall off.

[0014] As a preferred technical solution of the present application, the slots in the multiple columns are arranged longitudinally, and the lower end or the upper end of the slots is spaced a certain distance from the edge of the corresponding wall frame, and the spacing can at least accommodate one LED display screen block, and the adjustment screws B of the LED display screen block at the spacing can be inserted and removed into the base block for fixing;

[0015] Or multiple rows of slots are arranged horizontally, and the left or right end of the slot is at a certain distance from the edge of the corresponding wall frame, and the distance can at least place one LED display screen block, and the adjustment screw B of the LED display screen block at the distance can be inserted and removed into the base block for fixing;

[0016] When the side wall frame I, top wall frame II and bottom wall frame III are installed to form a rectangular space structure, some LED display screen blocks are inserted into the corresponding slots from the spacing, and then the LED display screen blocks to be installed at the spacing are inserted into the base block through the adjusting screws B.

[0017] As a preferred technical solution of the present application, the side wall frame I, top wall frame II, and bottom wall frame III are connected at the corresponding edges via multiple second frame units; the second frame unit is in the shape of an arc groove, and the inner wall is also equipped with multiple LED display screen blocks in the shape of an arc groove via corresponding base blocks; a third frame unit is provided at the corresponding top corner between the side wall frame I, top wall frame II, and bottom wall frame III; the third frame unit is in the shape of a one-eighth spherical frame, and its inner wall is equipped with multiple LED display screen blocks in the shape of one-eighth spherical via corresponding base blocks.

[0018] As a preferred technical solution of the present application, the base block is provided with a plurality of extended springs, each spring has a small ball at its end, and the plurality of small balls surround an insertion space. When the adjustment screw B of the corresponding LED display unit is inserted, the adjustment screw B extends into the insertion space, and the large end cap of the adjustment screw B abuts against the inner part of the small ball close to the insertion space, pressing the small ball outward to enlarge the insertion space and achieve insertion. After the insertion is completed, the insertion space is lowered under the action of the spring, thereby achieving position limiting; when pulling out, the small ball is also squeezed outward to enlarge the insertion space, thereby facilitating pulling out.

[0019] As the preferred technical solution of the present application, the top wall frame II is fixedly connected to the ceiling rod, and the side wall frame I is fixedly connected to the top wall frame II and supported on the ground; the bottom wall frame III is fixed to the ground separately by screws, and there is a gap between it and the side wall frame I, forming a separate setting structure.

[0020] As a preferred technical solution of the present application, the side wall frame I, top wall frame II, and bottom wall frame III are all formed by splicing multiple first frame units in an array arrangement; the first frame units are provided with transverse through holes and longitudinal through holes, and the transverse through holes of the first frame units in the same transverse row in the corresponding wall frame are positioned relative to each other and are penetrated by the same transverse rod, and the longitudinal through holes of the first frame units in the same vertical row in the corresponding wall are positioned relative to each other and are penetrated by the same longitudinal rod; there are gaps in the thickness direction between the transverse rod and the transverse through holes, and between the longitudinal rod and the longitudinal through holes; the transverse rod and the vertical rod are threadedly equipped with an adjusting screw A, and the adjusting thread A is a magnetic screw; by rotating the corresponding adjusting screw A to make the adjusting screw A magnetically contact with the first frame unit, the first frame units can be located in the same plane to form a planar adjustment structure.

[0021] As a preferred technical solution of the present application, the transverse rod and the first frame unit are fixed at the transverse through hole via locking screws, and the longitudinal rod and the first frame unit are also fixed at the longitudinal through hole via corresponding locking screws.

[0022] For ease of understanding, the core principles of this solution are explained:

[0023] 1. The LED display blocks are not easy to fall off and will not cause safety hazards;

[0024] a. In general immersive space display screens, the traditional LED display screen installation method is adopted, that is, the LED display screen block is magnetically adsorbed on the back frame through the magnetic screws on the back, but when the back of the magnetic screws is demagnetized, the LED display screen block is easy to fall off; b. In general immersive space display screens, the top wall frame, the top wall frame, and the bottom avoidance frame of the back frame are connected together. When people step on the bottom wall frame, it is easy to cause slight vibration of the entire back frame, and this vibration is also easy to cause the demagnetized LED display screen block to fall off;

[0025] In this solution: a. The adjusting screw B (i.e., magnetic screw) on the back of the LED display block is still magnetic, and its large end cap is inserted into the slot. Even if the adjusting screw B is demagnetized, the LED display block will not fall off - it will only bulge outward, and the staff can replace it in time; b. In this solution, there are also some adjusting screws B of the LED display block, which are inserted into the insertion space of the base block. Even if it is demagnetized, the adjusting screw B will still be flexibly limited by multiple small balls and will not fall off. The subsequent staff can replace it by pulling it outward; c. In addition, the bottom frame of this solution is not connected to the side wall frame, but has a certain gap, but the gap is The gap is small and does not affect people's perception. It is mainly to prevent the bottom frame from contacting the side frame. In this way, when people step on the bottom frame and cause the bottom frame to vibrate, the LED display screen blocks on the side frame and the top frame will not vibrate together, thereby preventing the LED display screen blocks on the side frame and the top frame from falling off; d. In the second frame unit and the third frame unit, the adjustment screws B on the back of the LED display screen block are also installed with the insertion space at the corresponding base block, and the corresponding LED display screen block will not fall off; e. In summary, the LED display block installation structure of this scheme makes it difficult for the LED display screen block to fall off, and will not cause the LED display screen block to fall off and hit people, thereby avoiding safety hazards;

[0026] Second, the side wall rack, top wall rack, and bottom wall rack are structures that facilitate flatness;

[0027] In the prior art, there are usually two ways to make a back frame: the first is to weld multiple rods as needed, and then fix the welded back frame on the wall, but this welding method is difficult to ensure the flatness of the back frame on the front; the second is to gradually connect multiple back frame units into an integrated back frame through bolts, and then fix the back frame on the wall as the front wall. This bolt connection method is also difficult to ensure the flatness of the back frame on the front; if the flatness of the back frame is not good, when the LED display screen block is magnetically adsorbed on the back frame to form a display screen on the entire wall, the flatness of the display screen can only be adjusted by the magnetic screws on the back of the LED display screen block (adjust the length of the magnetic screws on the back of the LED, and then let the magnetic screws be adsorbed on the back frame); but this method has a limited degree of adjustment and still cannot guarantee the flatness of the entire display screen particularly well;

[0028] In this scheme: a. the side wall frame I, the top wall frame II, and the bottom wall frame III are all formed by splicing a plurality of first frame units arranged in an array, and longitudinal through holes and transverse through holes are opened in the first frame units; when the plurality of first frame units are arranged in an array, the transverse rod is passed through each first frame unit in the same transverse column, and the longitudinal rod is passed through each first frame unit in the same longitudinal column, thus forming a side wall frame I / top wall frame II / bottom wall frame III as a whole; b. by rotating the adjusting screw A, the length of the adjusting screw A after being extended and resting on the first frame unit is different, so that the front of each first frame unit arranged in the array can be adjusted to a certain extent. To a certain extent, they can be well located in the same plane (so that when the LED display screen blocks are adsorbed and placed on the side wall frame Ⅰ / top wall frame Ⅱ / bottom wall frame Ⅲ, the flatness of multiple LED display screen blocks on a certain wall frame can be preliminarily guaranteed. Combined with the adjustment of the adjustment screws B on the back of the LED display screen blocks, the flatness of multiple LED display screen blocks on a certain wall frame can be further guaranteed, thereby improving the visual effect); c. After the adjustment is completed, the locking screws are used to lock and fix the horizontal rod, the vertical rod and the corresponding first frame unit, so that the side wall frame Ⅰ, the top wall frame Ⅱ, and the bottom wall frame Ⅲ form a whole with higher flatness.

[0029] The utility model has the following advantages:

[0030] (1) Through the structural design of the slot and the base block, even if the adjustment screw B on the back of the LED display screen block is demagnetized or demagnetized, the LED display screen block will not fall off, thereby preventing the LED display screen blocks at the side wall frame I and the top wall frame II from falling off and hitting people, thereby improving safety; in addition, since the bottom wall frame III is separated from the side wall frame I, when people step on the ground, the side wall frame I and the top wall frame II will not vibrate, thereby preventing the corresponding LED display screen blocks from falling off due to vibration;

[0031] (2) The flatness of the front of the side wall frame I, the top wall frame II, and the bottom wall frame III can be adjusted by adjusting the screw A, thereby improving the flatness of the front of the side wall frame I, the top wall frame II, and the bottom wall frame III; when the LED display screen block is subsequently adsorbed and placed, the adjusting screw B is used to adjust the flatness of the LED display screen block during placement; in this way, when multiple LED display screen blocks form an integral display screen on the front of the side wall frame I, the top wall frame II, and the bottom wall frame III, the overall display screen has good flatness, thereby improving people's visual experience.

[0047] The present invention is further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0048] It should be noted that the directions or positional relationships indicated by "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the utility model product is usually placed when in use, or are the directions or positional relationships commonly understood by those skilled in the art. Such terms are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the utility model.

[0049] It will be understood by those skilled in the art that, unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. It should also be understood that terms such as those defined in general dictionaries should be understood to have meanings consistent with those in the context of the prior art, and will not be interpreted with idealized or overly formal meanings unless specifically defined as here.

[0050] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0051] (Example 1)

[0052] like Figure 1-Figure 6 As shown, a mounting structure for a space display screen includes a side wall frame I, a top wall frame II, and a bottom wall frame III, which together form a rectangular space structure. The inner surfaces of the side wall frame I, the top wall frame II, and the bottom wall frame III are provided with LED display screen blocks. The back of the LED display screen block is provided with an adjusting screw B700, which is a magnetic screw. The adjusting screw B700 is magnetically adsorbed on the corresponding wall frame;

[0053] Among them, multiple rows of slots 800 are arranged on the inner walls of the side wall frame I, the top wall frame II, and the bottom wall frame III, and the adjusting screws B700 of the LED display screen block slide into the slots 800; the large end cap head of the adjusting screw B700 can be adsorbed on the bottom of the slot 800;

[0054] When there is vibration or insufficient magnetism, the large end cap head of the adjusting screw B700 can still be stuck in the slot 800, so that the LED display screen block will not fall off.

[0055] See also Figure 2-Figure 4 , the setting direction of the slots 800 is set: multiple rows of slots 800 are arranged in a longitudinal direction, and the lower end or the upper end of the slots 800 is at a certain distance from the edge of the corresponding wall frame, and the distance can at least place one LED display screen block, and the adjustment screws B700 of the LED display screen block at the distance can be inserted and removed into the base block 900 for fixing;

[0056] Or multiple rows of slots 800 are arranged horizontally, and the left or right end of the slots 800 is spaced a certain distance from the edge of the corresponding wall frame, and the distance can accommodate at least one LED display screen block, and the adjustment screws B700 of the LED display screen block at the distance can be inserted and removed into the base block 800 for fixing;

[0057] During operation, when the side wall frame I, top wall frame II, and bottom wall frame III are installed to form a rectangular space structure, some LED display screen blocks are inserted into the corresponding slots 800 from the spacing, and then the LED display screen blocks to be installed at the spacing are inserted into the base block 900 through the adjusting screws B700.

[0058] See also Figure 5 and Figure 6 , this embodiment designs the base block 900, specifically; in the base block 900, a plurality of extended springs 901 are arranged thereon, and a small ball 902 is arranged at the end of each spring 901, and a plurality of small balls 902 surround an insertion space. When the adjusting screw B700 of the corresponding LED display unit is inserted, the adjusting screw B700 extends into the insertion space, and the large end cap of the adjusting screw B700 will abut against the inner part of the small ball 902 close to the insertion space, pressing the small ball 902 outward, making the insertion space larger, and realizing insertion. After the insertion is completed, the insertion space becomes lower under the action of the spring 901, thereby realizing the limit; when pulling out, the small ball 902 will also be squeezed outward, thereby making the insertion space larger, so as to facilitate pulling out.

[0059] In this embodiment, refer to Figure 3 The positions of the slot 800 and the base block 900 are staggered, so that when the adjusting screw B700 on the back of the LED display block is inserted into the slot 800, the base block 900 will not cause any obstruction; therefore, the position of the adjusting screw B700 at the slot 800 on the back of the LED display block is different from the position of the adjusting screw B700 at the base block 900 on the back of the LED display.

[0060] In this embodiment, the top wall frame II is fixedly connected to the ceiling rod, the side wall frame I is fixedly connected to the top wall frame II and supported on the ground; the bottom wall frame III is fixed to the ground separately via screws, and there is a gap between it and the side wall frame I, forming a separate setting structure.

[0061] (Example 2)

[0062] See also Figure 6-Figure 12 , based on Example 1, the structures of the side wall frame I, the top wall frame II, and the bottom wall frame III are further designed;

[0063] In the side wall frame I, the top wall frame II, and the bottom wall frame III, the first frame units 100 are arranged in an array;

[0064] Between the side wall frame I and the top wall frame II, multiple second frame units 200 are connected at the corresponding edges. The second frame units 200 are in the shape of arc grooves, and multiple LED display screen blocks in the shape of arc grooves are also installed at the inner wall through corresponding base blocks 900;

[0065] Between the side wall frame I and the top wall frame II, a third frame unit 300 is provided at the corresponding top corner. The third frame unit 300 is in the shape of a one-eighth spherical frame, and a plurality of one-eighth spherical LED display screen blocks are installed on the inner wall thereof through corresponding base blocks 900;

[0066] A plurality of second frame units 200 are also connected and installed at the lower edge of the side wall frame I;

[0067] A third frame unit 300 is also connected and installed at the corner position of the lower edge of the side wall frame I;

[0068] The circumferential edge of the bottom wall frame III does not contact the second frame unit 200 and the third frame unit 300 at the lower edge of the side wall frame I, that is, there is a certain gap, and the gap is relatively small, with 1-2 mm being the best; so that when a person steps on the bottom wall frame III and causes the bottom wall frame III to vibrate, the vibration will not be transmitted to the side wall frame I and the top wall frame II.

[0069] See also Figure 8-Figure 12 , this embodiment specifically designs the structures of the side wall frame I, the top wall frame II, and the bottom wall frame III;

[0070] The side wall frame I, the top wall frame II, and the bottom wall frame III are all formed by splicing a plurality of first frame units 100 arranged in an array;

[0071] The first frame unit 100 has a transverse through hole 101 and a longitudinal through hole 102. The transverse through holes 101 of the first frame units 100 in the same transverse row in the corresponding wall frame are opposite to each other and are penetrated by the same transverse rod 400. The longitudinal through holes 102 of the first frame units 100 in the same longitudinal row in the corresponding wall frame are opposite to each other and are penetrated by the same longitudinal rod 500.

[0072] There is a gap between the horizontal bar 400 and the horizontal through hole 101, and between the vertical bar 500 and the vertical through hole 102 in the thickness direction; the horizontal bar 400 and the vertical bar 500 are threadedly matched with an adjusting screw A600, and the adjusting screw A600 is a magnetic screw;

[0073] In addition, the transverse rod 400 and the first frame unit 100 are fixed at the transverse through hole 101 by means of locking screws, and the longitudinal rod 500 and the first frame unit 100 are also fixed at the longitudinal through hole 102 by means of corresponding locking screws;

[0074] During operation: a. Place multiple first frame units 100 in an array on a flat ground to form multiple horizontal rows and multiple vertical rows, and align the first frame units 100 with each other - similar to a table; b. Pass a horizontal rod 400 through the horizontal through holes 101 in opposite positions in the first frame units 100 in the same horizontal row. If the first frame units 100 in the horizontal row have multiple horizontal through holes 101, multiple horizontal rods 400 are inserted, and the horizontal rods are inserted in each first frame unit 100 in each horizontal row in turn; c. Referring to the method in b above, insert the vertical rod 500 into the vertical through holes 102 of the first frame units 100 in the corresponding vertical row; d. Then screw the adjusting screw A600 into the threaded holes of the horizontal rod 400 and the vertical rod 500. , let the adjusting screw A600 rest on the first frame unit 100 to form an outward lifting force. In addition, the adjusting screw A600 is a magnetic dry and the corresponding part of the first frame unit 100 is magnetically conductive. Therefore, when the adjusting screw A600 is not in contact with the first frame unit 100, an adsorption force opposite to the lifting force can be generated; therefore, through such a positive and negative adjustment method, the first frame units 100 in the entire side wall frame Ⅰ / top wall frame Ⅱ / bottom wall frame Ⅲ can be positioned at a better flatness at the front; e. After the adjustment is completed, the corresponding cross bar 400 and the first frame unit 100, and the longitudinal bar 500 and the first frame unit 100 are locked and fixed at the positions of the transverse through hole 101 and the longitudinal through hole 102 using locking screws.

[0075] In this embodiment, refer to Figure 8 and Fig. 9 The cross bar 400 and the longitudinal bar 500 are U-shaped channel steel bars, and the bottom surface of the U-shaped channel steel bar is provided with a long waist-shaped hole along the length direction; the locking screw passes through the threaded hole of the first unit 100 and then penetrates into the long waist-shaped hole on the cross bar 400 or the longitudinal bar 500 and is locked.

[0076] In this embodiment, refer to Figure 8 and Fig. 9 The first frame unit 100 includes a rectangular frame 110 and an auxiliary strip 120, and the auxiliary strips 120 are arranged alternately in the rectangular frame 110; transverse through holes 112 and longitudinal through holes 102 are opened at different thickness positions at the edges of the rectangular frame 110; when the adjusting screw A600 is rotated, the adjusting screw A600 is in magnetic contact with the auxiliary strip 120.

[0077] Further, see Figure 4In the first frame unit 100, the front of the auxiliary bar 120 is flush with the front of the rectangular frame 110; the horizontal bar 400 and the vertical bar 500 are both arranged at the back of the auxiliary bar 120; the locking screws pass through the threaded holes on the edges of the rectangular frame 110 from the back and are locked and fixed with the corresponding horizontal bar 400 or vertical bar 500. Of course, according to needs, the locking screws can also be passed through the threaded holes on the edges of the rectangular frame 110 from the front and are locked and fixed with the corresponding horizontal bar 400 or vertical bar 500. This method is convenient for the subsequent adjustment of the entire side wall frame I, top wall frame II, and bottom wall frame III after being fixed to the corresponding wall, but it is generally not necessary.

[0078] In this embodiment, the second frame unit 200 is connected to the corresponding wall frame via bolts; the third frame unit 300 is also connected to the corresponding wall frame via bolts.

[0079] It should be noted that LED display screen blocks are arranged at the front of the side wall frame I, the top wall frame II, the bottom wall frame III, the second frame unit 200 and the third frame unit 300; an adjustable adjusting screw B700 is arranged on the back of the LED display screen block, and the adjusting screw B700 is a magnetic screw; after the adjusting screw B700 is rotated to a suitable length, the LED display screen block is placed by adsorption (it should be noted that the method of adjusting the LED display screen block by means of the magnetic adjusting screw B700 is a prior art, and many LED display screens in this field adopt this adsorption placement method).

[0080] The above embodiments only express the preferred implementation modes, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model.
